🔧 Fusion - Power Steering Pump Replacement

Your Fusion doesn’t use a hydraulic power steering pump. It uses EPAS (Electric Power-Assisted Steering), which is an electric motor and control module built into the steering gear (rack).

So there’s no pump to remove or replace—if the steering is hard or you have a warning, we diagnose the EPAS system and repair/replace the correct component instead.

Difficulty Level: Intermediate | Estimated Time: 0.5–2.0 hours (diagnosis); 3–6 hours (steering gear replacement if needed)

⚠️ Safety & Precautions

• ⚠️ Keep hands clear of steering parts with ignition ON (the EPAS motor can move suddenly).
• ⚠️ If lifting the car, always support it with jack stands on a level surface.
• ⚠️ Hybrid note: avoid orange high-voltage cables; do not unplug HV connectors.
• Disconnect the 12V battery negative terminal before unplugging EPAS connectors.

• Park on level ground, steering wheel centered, and set the parking brake.
• Turn the ignition OFF and wait 2 minutes before unplugging modules.
• Disconnect the 12V battery negative terminal using a 10mm socket.
• If you’re chasing a warning light, plan to scan codes first (before disconnecting the battery) using an OBD2 scan tool with Ford module access (specialty).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm what failed (important, since there’s no pump)

• Plug in an OBD2 scan tool with Ford ABS/PSCM access (specialty) and check for EPAS/PSCM trouble codes.
• Write down codes and freeze-frame data (it helps you avoid replacing the wrong part).
• If you see a message like “Steering Assist Fault,” that points to EPAS, not a pump.

Step 2: Check 12V power supply basics (common on hybrids)

• Open the hood and inspect battery terminals for looseness/corrosion using a flashlight.
• With the ignition OFF, disconnect the negative terminal using a 10mm socket.
• Low 12V can trigger steering assist faults.

Step 3: Inspect EPAS electrical connectors and harness

• Raise the front safely using a floor jack (rated 3-ton minimum) and support with jack stands (rated 3-ton minimum).
• Use a flashlight to inspect the steering gear’s electrical connector area for damage, water intrusion, or rubbed-through wiring.
• If needed, remove underbody panels using a trim removal tool and ratchet (fastener types vary by panel).

Step 4: If replacement is required: plan for steering gear (rack) replacement

• The EPAS motor/module is part of the steering gear—replacement is typically the full steering gear assembly.
• This job requires separating suspension/steering connections and then getting a wheel alignment afterward.
• Use a torque wrench for all steering fasteners during reassembly; Torque to factory specs (they vary by fastener and subframe configuration).
• If you want, I can give the full rack replacement steps.

✅ After Repair

• Reconnect the 12V battery negative terminal using a 10mm socket.
• Clear EPAS/PSCM codes using the OBD2 scan tool with Ford module access (specialty) and confirm they don’t return.
• Start the car and slowly turn lock-to-lock while stationary to verify smooth assist (no grinding, no warning message).
• If the steering gear/tie rods were replaced, get a 4-wheel alignment immediately.

Two quick questions so I guide you to the exact fix:

• Do you have a dash message like “Steering Assist Fault” or a warning light?
• Is the steering heavy all the time, or only at low speeds/when parking?
